Modeling electron transport in metallic single wall carbon nanotubes

First principles atomistic calculations of electrical conductance for single-wall metallic carbon nanotubes on copper electrodes are described. Density functional theory and a non-equilibrium Green's function technique are used to calculate electronic structure and current-voltage characteristics. The computed effects of selected impurities and nanotube strains on the conductance are displayed and discussed. Progress in studying the impacts of copper-nanotube interface characteristics on the electrical properties is reported.
